Повышение комплексности использования платиносодержащего медно-никелевого сульфидного сырья
On increasing the integration in the use of platiniferous copper-nickel sulphide ores
The authors consider the possibility of using the poor final mill tailings produced by Talnakh concentrating mill for production of the filling mixture instead of specially produced rock material. They propose a technological flow for extraction of precious metals from the mill tailings.
Повышение безопасности при разработке газоносных угольных пластов
On improving safety during the mining of gas-bearing coal seams
The author has established the dependencies between the residual pressure of methane and the basic influencing factors during the natural and artificial degassing of coal seams.

Mineral and primary resources of the Russian Far-East: comparative analysis of the regions of the Far-Eastern federal district
The authors provide the results of the analysis and the assessment of quantitative, qualitative and cost condition of the natural mineral resources mineable in the Far-Eastern region in comparison between the member territories of the Far-Eastern Federal District.
Правовые вопросы недропользования
Грамотно готовить ведомственные нормативные акты, связанные с недропользованием
On competent drafting of departmental normative acts related to subsurface resource management
The author provides well-reasoned comments to the structure, text, and the mechanism of execution of the regulations «Accounting of resource development costs» approved by the Ministry of Finance. He proposes adopting a new version of the regulations and eliminate the critical weaknesses, some of which contain factors creating propensity for corruption. He also proposes a number of measures aimed at creating the economic incentives for the companies conducting prospect evaluation surveys.

Вскрышные работы при разработке сложноструктурных россыпных месторождений
Stripping operations in the mining of placer deposits of complex structure
The authors consider the issues of outlining of the commercial reserves on top of the sand layer when mining placer deposits of complex structure. The designed optimal outline will ensure minimal sand loss during the stripping operations.
Повышение качества дезинтеграции высокоглинистых песков россыпных месторождений гидромеханическим способом
Improving the quality of the high-clayey sands disruption at placer deposits using the water-assisted technique
The authors have determined the relationships between the placer deposits sand moisture and composition on the efficiency of their disruption using the water-assisted technique. They propose a spiral desintegrator design which allows efficient washout of the clayish components.
Разработка обводненных месторождений с применением одноковшовой техники
Mining of water-bearing deposits using single-bucket machinery
The authors have designed a technique for two-bench rock excavation using the single-bucket machinery installed on a pontoon during the mining of water-bearing deposits without draining them. They also provide the basic mine parameters calculation.

Роль породной толщи в формировании очагов геодинамических явлений при разработке угольных пластов, на примере Баренцбургского месторождения
The role of the rock strata in geodynamical process zones formation during the coal seams mining by the example of Barentsburg coal deposit
The authors demonstrate the influence of the thick mass of solid durable sandstones in upper roofs upon formation of geodynamical process zones. They propose a method for efficient roof control by means of leaving extended holding pillars when working with long production faces, and groups of support pillars when mining in shortwalls.

Создание структурно-геометрической модели прибортового массива
Development of a structural and geometrical model of the flank-side mass
The authors provide the results of development of a structural and geometrical model of the flank-side mass for Akzhal deposit in Kazakhstan.
Моделирование пространственных переменных с помощью нейронных сетей (трёхмерный случай)
Spatial variables modeling using neural networks (3D situation)
The author considers the possibility of using artificial neural networks for creating a 3-dimensional mathematical model of a spatial variable of an ore deposit's transient geochemical field. He proposes an algorithm for searching a suitable neural net based on using a spatial isotropic variogram of model remainders and several adequacy criteria. The author also gives examples of building block models of the spatial variable components and visualizing some results obtained using such models.

Совершенствование методов дегазации горного массива при строительстве рудника «Удачный»
Improvement of rock massif degassing method during the construction of «Udachny» ore mine
The authors provide brief information about the gas conditions of the «Udachnaya» pipe deposit. They propose a number of measures to ensure safety of the mining operations during construction and operation of the mine under the conditions of gas saturation of the rock massif.
Экология
Типизация генеральных планов карьеров и оценка степени их экологичности
Typification of mine master plans and evaluation of their environmental compatibility degree
The author analyses the possible adverse impact of the open-cut mining method upon the natural environment in relation to the master plan of the mine. The environmental risk level is determined by the linear dimensions of the mine, availability and the volume of the tailing dump, placement of the refuse dump and the surface processing techniques used. He provides a qualitative (expert) assessment of the environmental risk for various mining systems depending on the volume of the extracted rock mass, original stock toxicity, and the transport used.

Исторические предпосылки возникновения идеи геометризации месторождений полезных ископаемых
Historical background of the idea of mineral deposits geometrization
The author demonstrates that the subsurface resources geometry as a mining science system discipline has been formed as a result of the mining operations' demand in volumetric representation of the prospecting data characterizing the shape, the properties and the concentration composition of the chemical elements in the mine rock.
